IMPROVEMENT IN lNSERTlBLE SAW-TEETH.
Specification forming part of Letters Patent No. l77,4Sl dated May 16, 1876; application filed April 29, 1876.
a crosscut-saw, teeth which can be readily removed when worn or broken, to make way for new teeth; andthis object 1 attain in the manner which I will now proceed to describe, reference being had to theaccompanying drawing, in which- Figure 1 represents part of the blade of a crosscut-saw with detachable teeth, and Fig. 2 a section on the line 1 2. v
The base of the tooth A consists of a segment, at, of a ring, terminating at the ends in angular cutters b b, the inner edges of which are, by preference, slightly inclined, the outer edges being more abruptly inclined, and in all cases in the contrary directions, as shown.
In the blade B are made, at proper intervals, recesses d, adapted to the bases at of the teeth, V shaped grooves being made in the latter to receive the V-shaped rib 6, made on the edge of the recess.
By applying a suitable'instrument to holes it, made in the tooth, and forcing the cutting-points towardeach other, the base a may be so far contracted as to permit its in- In order to prevent the base of the tooth from turning in the recess, I make, at the junction of each cutter with the segmental base, a shoulder, m, for hearing against a shoulder, at, on the blade.
The facility with which a damaged tooth can be removed to make way for a new one will be readily understood Without explanation.
I claim as my i nvention- The within-described duplex tooth, consistin g of a segmental base, terminating in cutters b b, inclined in contrary directions, the whole Peing adapted to a recess in the blade, as set orth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
